San Antonio electricity: one provider, CPS Energy
CPS Energy is owned by the City of San Antonio and is one of the largest city-owned utilities in the country, selling both electricity and natural gas across San Antonio and most of Bexar County. Its rates are set by its board and the city council.
When Texas opened its electricity market in 2002, city-owned utilities and electric cooperatives were allowed to join but not required to, and almost none have: Lubbock, in 2024, was the first city to do it, and Nueces is the only co-op. CPS Energy still buys or generates the power, owns the wires and meters, and sends one bill, with rates set locally rather than by competing offers.
What this means for your bill
One bill, from CPS Energy, at rates it sets. There are no plans to compare, no contract to time and no early termination fee to weigh. Sites that list “San Antonio electricity plans” are showing the plans sold in the choice areas nearby; an address on CPS Energy’s lines can’t enroll in them, and we don’t pretend otherwise.
What you can do is ask CPS Energy about its own rate options and its efficiency and rebate programs, and work on the usage: in a Texas summer most of the bill is air conditioning.
Check: is your address really on CPS Energy’s lines?
Utility borders don’t follow city limits. A few addresses in and around San Antonio can be on a neighboring utility's lines. The surest check is the bill: the company that sends it is the company that serves you. If it names Oncor, CenterPoint Energy, AEP Texas, TNMP or Lubbock Power & Light as the delivery company, you can choose, and every plan sold at that address can be priced on your own 12 months.
San Antonio electricity FAQs
Can I choose my electricity provider in San Antonio?
No. CPS Energy is the only electricity provider for addresses on its lines, and there is no retail plan to switch to. Comparison sites that list plans for San Antonio are showing plans sold in the delivery areas around it; a San Antonio address on CPS Energy's lines can't enroll in them.
Why doesn't San Antonio have electricity choice?
When Texas opened its electricity market in 2002, city-owned utilities and electric cooperatives were allowed to join but not required to, and almost none have: Lubbock, in 2024, was the first city to do it, and Nueces is the only co-op. CPS Energy still buys or generates the power, owns the wires and meters, and sends one bill, with rates set locally rather than by competing offers.
Who do I call about an outage or a bill in San Antonio?
CPS Energy, for both. It owns the wires, sends the crews and issues the bill, so there is no second company involved. The number is on the bill and on its website.
Will San Antonio get retail electricity choice?
Only if the city decides to join the competitive market, as Lubbock did in 2024. That is a decision for the city council and the utility's board, not the state, and none has been made for San Antonio as of this writing.
How do I lower my electricity bill in San Antonio?
Without plans to compare, the bill comes down to usage and the utility's own options. Ask CPS Energy about its rate structures (some city utilities offer time-of-day or budget-billing options), its efficiency and rebate programs, and any payment arrangements. Air conditioning is most of a Texas summer bill, so the thermostat, attic insulation and a serviced unit are where the usage goes.
